That discussion was about local notifications, where indeed the
situation is like you describe.

But Andreas asks about calling remote handlers, about which we by
definition know much less.  In that context, it might indeed make
sense to pass the file, not its parent directory, because the handler
can easily reconstruct the parent directory if that's what it needs.
By contrast, there's no way for the handler to intuit the file which
was stripped.

WDYT?
